1. Introduction
The Rhode Island Residential Stretch Code is an important part of a comprehensive effort to
reduce long-term energy consumption, support Rhode Island’s growing green economy, increase
the affordability of home utility costs, and meet the state’s greenhouse gas (GHG) reduction
targets which aim to reduce statewide GHG emissions to 80% below 1990 levels by 2050 (§ 42-
6.2-2). As referenced in National Grid’s Zero Energy Buildings white paper, establishing zero-
energy building energy codes in Rhode Island by 2035 will be an important component to
achieving these goals. This Residential Stretch Code is meant to serve as a stepping stone
towards these ambitious targets.
As directed in the Governor’s Lead by Example Executive Order (EO 15-17), the Office of
Energy Resources led in the development of this document. Its overarching purpose is to provide
a uniform set of provisions that will help bridge current construction practices to widespread
development of high performance and zero energy buildings.
The Rhode Island Residential Stretch Code
(hereafter “Residential Stretch Code”) is a
voluntary code that provides guidance and best-
practice requirements intended to reduce the
negative impacts and increase the overall positive
impacts of the built environment. It is consistent
with the Rhode Island Office of Energy Resources’
mission to lead Rhode Island to a secure, cost-
effective, and sustainable energy future and
supports the Governor’s energy efficiency and
renewable energy goals for State-owned facilities
(EO 15-17).
This code establishes provisions that adequately
protect public health, safety, and welfare; do not
unnecessarily increase construction costs; do not restrict the use of new materials, products, or
methods of construction; and do not give preferential treatment to particular types or classes of
materials, products, or methods of construction.
This document is designed to be used by all individuals and organizations interested in the
construction of higher-performance homes. Builders, developers, architects, and homeowners are
encouraged to comply with all provisions of this code and receive recognition for obtaining
higher performance levels. The code can also be used as a guide for higher-performance
construction and renovations without achieving compliance with the entire code. Code officials,
at their own discretion, may accept compliance with the energy efficiency provisions of this
code, as a compliance path for similar provisions in the base Residential Building Code, SBC-2,
and Residential Energy Code, SBC-8. This authority is given to code officials in section
STRETCH CODES
Stretch codes can be employed in
addition to base codes to guide the
construction of buildings that use less
energy, have less negative impact on
the environment, and achieve higher
levels of occupant health and comfort.
Stretch codes encourage the use of
best practice design and construction
approaches that take advantage of
advances in building science and
technology.

R102.1.1 of Rhode Island’s current (2017) Residential Building Code (SBC-2) and Energy
Conservation Code (SBC-8).
The Residential Stretch Code is based heavily on the elements of the US Department of Energy
(DOE) Zero Energy Ready Homes (ZERH) program and the US Environmental Protection
Agency’s (EPA) WaterSense program.1 In addition to energy and water efficiency, this code also
addresses indoor environmental quality and comfort as well as operations and maintenance for
building systems, appliances, and components. Homes built to this code are also ready for the
installation of renewable energy systems and electric vehicle charging stations. This code
contains clear and specific provisions that align with all regulations promulgated by the State
Building Code Standards Committee and maximize the incentives available from Rhode Island’s
nation-leading energy efficiency programs. Consistent with State residential base codes, it will
be updated to allow for new construction methods and technologies to be incorporated at least
once every three years. Buildings that comply with the Residential Stretch Code are expected to
use less energy and water, have less negative impact on the environment, and achieve higher
levels of occupant health and comfort.

2. Applicability, Compliance, and Relationship to Other Codes
The Residential Stretch Code is a voluntary code that is meant to support developers, architects,
engineers, and builders interested in improving the sustainability, health, and comfort of the built
environment. Compliance with this document allows users to maximize incentives from
available energy efficiency programs and to gain recognition for their efforts from the state. The
provisions of this code apply to the new construction or renovation of residential buildings as
defined by the Rhode Island Building Code SBC-2:
Detached one- and two-family dwellings and multiple single-family dwellings
(townhouses) not more than three stories in height with a separate means of egress, and
their accessory structures.
All other buildings fall under the jurisdiction of the Rhode Island Commercial Building Code
SBC-1 and its related Energy Conservation Code (SBC-8) and Commercial Stretch Code. The
following Rhode Island Building Code Commission website includes details regarding Rhode
Island Codes: http://www.ribcc.ri.gov/.
This code is designed to be used in conjunction with Rhode Island base building codes: SBC-2
(Residential Building Code); SBC-3 (Plumbing Code); SBC-4 (Mechanical Code); SBC-5
(Electrical Code); and the residential provisions of SBC-8 (Energy Conservation Code). The
Residential Stretch Code does not replace any existing codes or regulations in effect, and there is
no previous version of this 2017 Residential Stretch Code.
The developers of this code have researched several model codes and high-performance building
programs and have incorporated the best features into the compliance paths. The US Department
of Energy (DOE) Zero Energy Ready Homes program is referenced as the principal energy
performance compliance path, and the US Environmental Protection Agency’s (EPA)
WaterSense program is referenced as a compliance path for water use efficiency. In all cases,
alternative compliance options are available.
Each of the referenced programs maintains a list of definitions. It is the responsibility of the user
of this code to review the definitions used by specific programs referenced within this code,
unless a definition is explicitly provided within this document.
Compliance verification. Compliance with the provisions of the stretch code is demonstrated
through a verification process. Each of the certification programs recognized as compliance
paths for energy efficiency (DOE ZERH, LEED, Passive House, and Living Building Challenge)
has its own verification process, and documentation of compliance with the selected program
shall be submitted to the Rhode Island Office of Energy Resources.
To verify compliance with the stretch code without completing a certification program, it is the
responsibility of the applicant to provide documentation of third-party verification. A signed
statement of compliance from a Residential Energy Specialist must be submitted with the
applicable checklists included in the Residential Stretch Code Compliance Packet. Residential
5
Energy Specialists shall have at least three (3) years of building design or construction
experience, and shall possess at least one of the following professional certifications:2
• Residential Energy Services Network (RESNET) ‒ Home Energy Rating System (HERS)
Certified Rater
• Building Performance Institute (BPI) ‒ Certified Building Analyst, or Certified Energy
Auditor
• Association of Energy Engineers (AEE) ‒ Certified Energy Manager or Certified Energy
Auditor
Compliance with non-energy provisions of the Stretch Code is verified by completing and
submitting a signed copy of the checklist(s) included in the Residential Stretch Code Compliance
Packet.
Figure 1 summarizes the process and options for compliance with this code.
2 Links to the referenced certification programs are included in Appendix A.

Additional Information:
• All projects must also comply with all current applicable Rhode Island base codes.
• When using alternative compliance paths, it is the responsibility of the applicant to
arrange for the verification of performance levels equivalent to the main compliance
paths.
• Please be sure to comply with all requirements listed in this document as well as the
requirements published for selected compliance paths.

3. Effective Use of This Code
It is recommended that building practitioners and/or project owners do the following:
• Inform the building department/code official of the intent
to follow the Residential Stretch Code prior to or at the
time of permit application. As allowed in sections
R102.1.1 of the Rhode Island Residential Building Code
(SBC-2) and Energy Conservation Code (SBC-8), the
code official may, at their discretion, use verification of
the energy efficiency portion of this code as a compliance
path for the energy efficiency provisions of the base
codes.
• Review the compliance path options and develop a
compliance plan, including downloading all relevant
program documentation and verifying that the project will
meet the criteria.
• Utilize the compliance checklist included in Appendix B
and in the compliance packet to track compliance
progress and include it with final documentation for the
code official and the homeowner.
• Contact National Grid and communicate the intent to
follow the Stretch Code (and interest in participating in
National Grid’s efficiency programs) prior to finalizing design documents and starting
construction. Appendix A includes links to information for National Grid’s technical
assistance and incentive programs.
• Investigate tax credits and other incentives available for renewable energy systems and
electric vehicles. Appendix A includes links to renewable energy programs available in
Rhode Island.
R102.1.1 ABOVE-CODE PROGRAMS
The following excerpt is from Rhode
Island’s current (2017) base code, and
gives code officials the authority to
accept compliance with this stretch
code document as a compliance path
for the energy efficiency provisions of
the base codes: “The code official or
other authority having jurisdiction shall
be permitted to deem a national, state,
or local energy efficiency program to
exceed the energy efficiency required
by this code. Buildings approved in
writing by such an energy efficiency
program shall be considered in
compliance with this code. The
requirements identified as ‘mandatory’
in Chapter 11 [SBC-2] or Chapter 4
[SBC-8] shall be met.”

National Grid Stretch Code Support
National Grid offers no-cost services and incentives
to help build energy efficient homes with lower
operating costs and increased durability, comfort,
and safety. They are available as follows but are
subject to change.
• Technical assistance ‒ Working in
partnership with the owner and/or builder,
the Residential New Construction (RNC)
Program offers energy modeling, design
assistance, and in-field inspections to help
customers achieve energy efficient homes.
• Financial incentives ‒ The RNC Program
offers whole-house performance incentives
in addition to rebates for qualifying high efficiency heating, cooling, and hot water
equipment.
To learn more about National Grid’s new construction services, call 888-887-8841.
Innovation
Innovative approaches and alternative materials, designs, and methods not specifically addressed
in this code can be approved by the code official where the proposed innovative approaches or
materials, designs, or methods comply with the intent of the provisions of the code. However, the
building practitioners and/or project owners shall be responsible for demonstrating equivalency
if alternative approaches are employed.
WHY IS NATIONAL GRID INVOLVED?
An important premise of National Grid’s
new construction program offerings is
to prepare building design and
construction practitioners for future
advancement in the energy efficiency
requirements of the state building code.
The Rhode Island Stretch Code shares
this premise, and National Grid’s new
construction programs have been
designed to complement the energy
aspects of this code where possible.
10
4. Energy Efficiency
4.0 General. This chapter addresses the energy
performance of the home and presents alternative
paths for compliance.
4.1 Scope. The provisions of this chapter regulate
the design, construction, commissioning, and
operation of buildings and their associated building
sites for the effective use of energy.
4.2 Intent. This chapter is intended to provide
flexibility to permit the use of innovative
approaches and techniques to achieve the effective
use of energy and to facilitate the construction of
zero net energy homes when renewable energy
systems are incorporated into the design or are
planned for future installation.
4.2.1. Design and construction incentives. National Grid offers technical assistance and
financial incentives through its electric and natural gas efficiency programs for many of
the requirements included in this chapter. Please refer to Appendix A for links to
National Grid’s incentive programs.
4.3 Application and compliance. Buildings and their associated building sites shall comply with
all provisions of the Rhode Island Residential Building Code (SBC-2) and all provisions within
Sections 4, 5, 6, 7, and 8 of this code or alternative compliance paths as described throughout
this document.
4.4 Energy performance. Compliance with the DOE Zero Energy Ready Homes National
Program Requirements (Rev. 06,)4 with Rhode Island amendments is required for compliance
with this code. Alternative compliance paths, as specified in Section 4.8 of this code, may also be
used to demonstrate compliance. ZERH program homes are verified by a qualified third party, as
defined in the ZERH program documentation. According to the DOE, ZERH program homes are
a minimum of 40%‒50% more energy efficient than a typical new home on a national average
basis. Compliance may be verified through either a prescriptive or performance path.
4.4.1 ZERH prescriptive path. The prescriptive compliance path specifies provisions
that must be met for insulation levels, air sealing, fenestration performance, lighting,
HVAC systems, appliances, and miscellaneous energy-using systems. The prescriptive
path provides a single, comprehensive set of required measures. Modeling is not required,
but no measure tradeoffs are allowed.
4 Rev. 06 is the current version of the ZERH program at the time of adoption of this code. Any revisions to this or other Stretch Code requirements will be issued as amendments to this code and detailed on the Rhode Island Office of Energy Resources Website: http://www.energy.ri.gov/.
USE OF THIS CHAPTER FOR
COMPLIANCE WITH SBC-8; ENERGY
CONSERVATION CODE
Compliance with this chapter is
intended to result in improved energy
performance compared with the
residential provisions of SBC-8. At the
discretion of the code official having
jurisdictional authority, compliance with
the energy efficiency provisions of this
code can be used to demonstrate
compliance with the residential
provisions of SBC-8.
11
4.4.2 ZERH performance path. The performance compliance path option requires that
“mandatory” prescriptive provisions be met, but it allows for the modeling of overall
building performance to demonstrate that the proposed building will use no more energy
than a similar building constructed in compliance with the prescriptive path.
4.5 DOE ZERH program design intent.5 ZERH certified homes are intended to be designed
and constructed to a standard that allows them to achieve zero net energy status, on an annual
basis, following the installation of an on-site renewable energy system ‒ typically, a photovoltaic
(PV) solar electric system. This code does not require the installation of such a system at the time
of construction but encourages the use of renewable energy and requires that the home be PV
installation ready as stipulated in Section 4.6.
4.6 RI Amendment – Renewable Ready. For compliance with this code, the provisions in this
section replace the Requirement 7 (Renewable Ready and PV Ready Checklist) provisions in the
DOE ZERH program.
The Rhode Island Residential Stretch Code does not require but does encourage the installation
of renewable energy systems at the time of home construction. Recognizing that the vast
majority of renewable systems installed on ZERH certified homes will be solar PV systems, it is
required that the homes include PV ready features.
4.6.1 Solar site evaluation. Prior to construction, the applicant must obtain a minimum
of one solar site evaluation from a solar installation firm that holds the following
credentials: a Rhode Island Contractors’ Registration and Licensing Boards registration,
proof of registration with the Rhode Island Secretary of State’s Office, and a Rhode
Island Renewable Energy Professional Certificate and/or a Valid “A” Electrical license.
The site evaluation must detail the location of the roof- or ground-mounted PV panels
and evaluate shading factors affecting system performance.
4.6.2 PV installation preparation. To facilitate PV installation, homes not initially
constructed with renewable energy systems shall be prepared for future installation.
Preparation shall include at least the following steps. An installation checklist is included
with the stretch code compliance packet:
5 Appendix A includes links and contact information for this and other referenced programs.
12
PV Installation Preparation Requirements
Install two 1” minimum diameter EMT conduits from the main electrical panel location to the attic
or other area easily accessible to the PV panel’s proposed location. Conduits for future PV
installations are to be capped and labeled at both ends.
Alternative: Install conduits as specified on a proposed PV installation plan from a credentialed
installation firm.
Install a 70-amp dual pole circuit breaker in the electrical service panel dedicated for use by a PV
system.
Alternative: Provide a labeled slot for a double-pole breaker in the electrical service panel.
For roof-mounted systems – Provide code-compliant documentation of the maximum allowable
dead load and live load ratings of the proposed roof. The roof structure dead load rating shall
support an additional 6 lb/sq ft for future solar system and shall meet all Rhode Island Building
Code requirements as required by the local code official.
For ground-mounted systems – Possible locations of the panels must be identified in the submitted
construction plans and be supported by a solar site evaluation. At least one potential location must
be identified in the construction plans for the future installation of the panels.
4.7 RI Amendment – HVAC Thermostats. The following provisions are required in Rhode
Island when using the ZERH program for compliance with this code:
4.7.1. Wireless “smart” thermostat ‒ For the control of HVAC systems, wireless
“smart” thermostats as defined by the ENERGY STAR program and meeting the
requirements of National Grid’s Residential New Construction Program must be
installed.
4.7.1.1 Exception. For homes utilizing ductless heat pump systems for heating and/or
cooling, a thermostat meeting the requirements of 4.7.1 may be installed. For ductless
heat pump installations, a wall-mounted thermostat compatible with the heat pump
may be installed rather than a wireless “smart” thermostat. Handheld remote controls
do not meet the thermostat requirements of this code.
4.8 Alternative energy efficiency paths. In addition to ZERH certification, alternative paths
may be used to comply with the energy efficiency requirements of this code: US Green Building
Council’s Leadership in Energy and Environmental (LEED) for Homes, Passive House, and the
Living Future’s Living Building Challenge. However, each of these three certifications differ in
their scope and methodology. To use them for compliance with this code, it is the
responsibility of the applicant to demonstrate, and supply a form of third-party verification
allowed by this code, that the performance features of the home will result in energy usage
equal to or lower than that required to obtain ZERH certification. If compliance with this
code is being used to demonstrate compliance with the energy efficiency provisions of the base
building code (SBC-2) or the energy code (SBC-8), applicants should discuss with the code
official the intent to comply with this code and any alternative compliance paths to be followed.
4.8.1 LEED for Homes. LEED for Homes is a voluntary program that promotes the
design and construction of efficient homes. The program includes both mandatory and
13
optional requirements. Achieving LEED certification and meeting the prescriptive or
performance energy efficiency requirements of the DOE ZERH program is an option for
complying with this stretch code.6
LEED for Homes can be used for both single-family homes and multifamily projects. The
mandatory energy and atmosphere requirements for this program include a maximum
HERS index and a completed Energy Star Qualified Homes Thermal Bypass Checklist.
Higher levels of performance and a lower HERS rating are obtained by complying with
selected optional requirements. Applicants should discuss with the code official the
particular set of LEED requirements proposed for the project prior to construction.
4.8.1.1 LEED certification pathways. To acquire LEED certification, all homes
must first meet three prerequisites related to energy and the atmosphere. These
include meeting minimum energy performance, acquiring appropriate energy
metering tools, and educating the homeowner, tenant, or building manager.
The program includes separate but similar checklists of aspects for single-family
homes and multifamily projects. Credits are awarded for each aspect that is met. Once
projects are completed, verifiers aggregate points that have been attained to provide a
LEED certification score. This score enables the USGBC to grant the home one of
four increasing levels of certification (certified, silver, gold, and platinum).
4.8.2 Passive House. Passive House is a certification standard that includes rigorous
standards for the design and construction of ultra-low energy homes. ZERH certification
is currently a requirement for Passive House certification, and in many ways, Passive
House goes above and beyond the requirements of this code. All other provisions of the
stretch code must be met as described within this document. The intent to use Passive
House for code compliance should be discussed with the code official or third-party
verifier prior to construction.
Passive House largely focuses on creating buildings that require minimal energy used for
heating or cooling. Insulation levels, air tightness, ventilation, windows and doors, space
heating, lighting and electrical appliances are all addressed in the program requirements.
6 The current ZERH prescriptive and performance path requirements can be found at https://energy.gov/eere/buildings/downloads/doe-zero-energy-ready-home-national-program-requirements-rev-06.
14
4.8.3 Living Building Challenge. The International Living Future Institute’s Living
Building Challenge provides a set of highly rigorous guidelines for energy efficiency.
The program objectives include reducing ecological harm and repairing environmental
damage through aggressive standards. A Living Building Challenge certification can be
used as an alternative path for compliance with the energy and water efficiency
provisions of this code; all other provisions of the stretch code must be met as described
within this document.
Homes can achieve the Living Building Challenge at an affordable cost through the
Living Building Challenge Framework for Affordable Housing. “Petals” are awarded for
implementing rigorous standards of sustainability. The energy petal, in particular,
requires projects to capture 105% of their total energy needs through on-site renewable
energy without the use of on-site combustion. Projects must also provide viable on-site
energy storage for resilience purposes.
5. Water Efficiency
Water is an integral component of any home’s energy use. Conservation of water resources is
especially vital towards its continued sustainability in Rhode Island. This stretch code
incorporates various methods by which homeowners can ensure efficient distribution and
availability of water. To comply with this stretch code, verification of compliance7 with the
provisions of the 2017 version of the US Environmental Protection Agency’s (EPA’s)
WaterSense program, or an equivalent alternative compliance path, is required.
The EPA’s WaterSense program helps consumers save water and maximize efficiency. The
program was designed to encourage water efficiency through voluntary action and to promote
products that use less water. Major or minor lifestyle changes by the consumers are therefore not
necessary to become more efficient. Instead, products and irrigation professionals are awarded
certifications based on their ability to fulfill certain efficiency and training criteria. These
specifications are applied to water used for both interior and exterior/landscaping purposes.
5.1 Interior. The following components of a home are covered by the WaterSense indoor
criteria:
• Service pressure
• Toilets
• Bathroom faucets
• Showerheads
• Hot water delivery systems
7 Applicants may provide a copy of WaterSense certification, or if they not obtaining certification may complete the WaterSense checklist and have it signed by the licensed plumber responsible for the installation of the plumbing fixtures.
15
• Dishwashers
• Clothes washers
• Evaporative air conditioners
• Water softeners
• Drinking water treatment systems
• Whole house humidifiers
5.2 Exterior/landscaping. On average, 30% of a home's water is used outside, although this
percentage can increase greatly during summer in arid climates. Monitoring and controlling
water systems outdoors is a particularly important aspect of managing residential water use
outside.
The following components of a home are covered by the WaterSense outdoor criteria:
• Landscape designs
• Mulching
• Pools/spas
• Ornamental water features
• Irrigation system designs
• Irrigation controllers
• Sprinkler heads
• Micro-irrigation systems
• Schedules
5.3 Optional paths to WaterSense for water compliance. Aside from EPA’s WaterSense
program, there are additional programs related to residential water usage that may be used to
comply with the water efficiency requirements of this code. Three programs ‒ LEED for Homes,
Living Building Challenge, and Enterprise Green Communities‒ offer concrete guidelines for
designing and managing water efficient systems in homes. However, these three certifications
differ in their scope and methodology. To use these alternative paths for compliance with this
code, the applicant may use the documentation checklist or specifications for the referenced
program and submit a copy signed by the licensed plumber responsible for the installation of the
plumbing fixtures.
5.3.1 LEED for Homes. LEED for Homes utilizes a credit system whereby points are
awarded for water efficiency. Credits are earned depending on the compliance path
chosen. The EPA WaterSense program is referenced as a compliance path; stretch code
applicants may document equivalent water efficiency performance.
5.3.2 Living Building Challenge. Homes can achieve the Living Building Challenge’s
water petal at an affordable cost through the Living Building Challenge Framework for
16
Affordable Housing. The water petal requires projects to work in harmony with the
natural water flows of the building site and its environment.
Projects must obtain 100% of their water needs from captured precipitation or other
natural closed-loop water systems or by recycling used water. Additionally, water must
be purified without the use of any chemicals. Any stormwater and water discharge must
be treated on-site and managed through re-use, a closed system, or infiltration.
5.3.3 Enterprise Green Communities
Enterprise Green Communities aims to increase residential water efficiency, with an
emphasis on affordable housing. Enterprise’s water conservation standards utilize many
of the EPA’s WaterSense guidelines and recommend WaterSense certified products. If
using the water guidelines for this program for stretch code compliance, the applicant
must provide third-party verified documentation that the performance features of the
home will result in water usage equal to or lower than that required to obtain the EPA’s
WaterSense certification.
6. Electric Vehicle Readiness
Electric vehicles (EVs) are predicted to be a critical part of a sustainable energy future, and the
ownership rate of EVs is increasing dramatically with new models being introduced every year.
Some simple provisions installed at the time of new construction will make it easier and less
intrusive to add electric charging stations at residences in the future. EV residential charging
stations fall into two categories: Level 1 charging, which operates on a 120-volt circuit, and
Level 2, which operates on a 240-volt circuit. Level 2 charging stations charge the batteries
much faster and are now considered the standard for EVs. A specification also exists for Level 3
charging, but Level 3 charging stations use high voltage (480V) dc circuits and are applicable to
commercial/industrial facilities and specialty charging stations.
6.1 Charging station readiness. Each single-family home, or at least one home in a two-family
dwelling, must be constructed with the capability to easily add a Level 2 charging station
immediately upon occupancy or at some future time. For multifamily residences falling under the
jurisdiction of the Rhode Island Residential Building Code (SBC-2), at least 25%, but never less
than one, of the parking spaces must be made EV ready.
For compliance with this code, the charging station preparation must include, at a minimum:
• A Raceway (conduit) to accommodate a 240V 40-amp circuit (level 2) which terminates
at an electrical circuit panel at one end and in a garage or at an exterior parking location
at the other end.
• The installation of an approved electrical enclosure at the future charging station.
• The labeling of a dedicated double pole 40-amp circuit breaker location in the main
electrical distribution panel or subpanel.
17
All installations must be completed by a licensed electrician and meet all Rhode Island electrical
base code requirements.
7. Indoor Environmental Quality (IEQ)
To promote healthy indoor environments, this code includes simple requirements related to
indoor air quality:
• Ventilation rates ‒ Each of the available energy efficiency paths within this code includes
guidelines for ventilation rates and control.
• Operations and maintenance ‒ This code requires that operations manuals (see Section 8
of this code) be supplied to the homeowner for all systems and appliances. Properly
following the recommended maintenance procedures ‒ especially for the cleaning and/or
replacement of air filters ‒ is critical for dust control.
• Limiting the volatile organic compound (VOC) content in interior building products,
components, and finishes ‒ Conventional paints, varnishes, oils, carpets and carpet
padding, plywood, plastics, and other surface finishes typically contain VOCs. Because
they are “volatile,” VOCs escape to the air over time. Nearly all categories mentioned
above are now offered in no-/low-VOC formulations, and suppliers now routinely publish
VOC levels as part of their marketing literature.
Compliance options. For compliance with this code, certification with the EPA Indoor AirPLUS
is a requirement of the ZERH Program certification. If following an alternative compliance path
for energy, applicants may obtain Indoor AirPLUS certification separately, or may meet the
VOC content criteria of one of the following programs or an equivalent. The checklist in the
compliance packet must be completed and signed by the applicant.
Greenguard. Certifies both residential and commercial products for VOC levels and provides a
free tool (SPOT) for identifying qualifying products.
Cradle to Cradle. Also operates a certification program with product search capabilities.
Health Product Declaration (HPD). HDP publishes a User Guide to meeting the indoor
product requirements of green building programs.
Declare. This is a component of the Living Building Challenge and provides guidance and a
product database.
8. Operations and Maintenance
Many homes and other buildings built to a high energy efficiency level do not achieve their
energy savings potential due to operational issues. The intent of this set of requirements is to
help ensure that homes built to the Rhode Island Stretch Code standard perform as intended and
deliver significant savings over their lifetime.
18
8.1 Owner’s manual. Prior to or at the time of first occupancy, the contracting team shall
provide an owner’s manual to the residents. The manual must include, at a minimum:
• A description of all energy-using systems and appliances in the home.
• The manufacturer’s operating manual for each system and appliance.
• Manufacturer’s instructions for all thermostats.
• The required solar site evaluation and a description of the PV ready conduit installed.
• A description of the EV charging station preparation that was installed.
• Brochures for the finishes (paints, stains, varnishes, carpet, etc.) that are present in the
home.
• Manufacturer’s instructions/operating manual for all safety equipment such as smoke,
fire, carbon monoxide, radon detectors, and fire extinguishers.
• Manufacturer’s instruction for any “smart” home energy management systems such as
smart hubs, networked lighting controls, etc.
8.2 Energy efficiency and renewable energy incentives. Prior to or at the time of first
occupancy, the builder shall provide the residents with an information packet describing the
current opportunities available through utility and government sources supporting energy
efficiency improvements and the installation of renewable energy systems.
